Versionless: Investigate install/repo feature resolutions paths and dependencies

[cbridgha]

The install commands are all located in

/com.ibm.ws.install
/com.ibm.ws.install.featureUtility

ResolveDirector is a bridge between install and kernel FeatureManager.
Product is the class that models the current "Local installed Liberty instance"

But ultimately the install code relies on the code in /com.ibm.ws.repository.resolver project that uses a KernelResolverRepository - a repo represents both remote ESA features... and "installed" kernel features.
And uses a class RepositoryResolver to resolve features using this repo instance.

Closing this as finished after creating:

• Versionless features impact on Liberty repository
• Versionless support for featureUtility
